High Velocity Oxy-Fuel ( HVOF ) system

For more than 15 years, Dura-Metal have been working successfully in the field of HVOF coating to restore worn out parts and also working with OEM to develop wear resistance coating applications.

We are pleased to introduce our economical, robust, lightweight and excellent quality Durajet HV 3000 HVOF system. HV 3000 powder thermal spray system melts metallizing powder by heat generated through combustion of fuel gas and oxygen. The metallizing powder is fed at a regulated rate of speed to a flame-spraying torch that may be hand-held or motion-controlled. A continuous flow of compressed air surrounds the flame, atomizes the molten metal and disperses it over the surface of the object to be coated. The spraying torch may be guided by hand for spraying large or intricate pieces; for production work the torch may be mounted to programmable equipment, such as an x-y manipulator or robotic arm. The HV 3000 Powder torch combines a patented gas valve with unique flame pattern that results in greatest efficiency for depositing high-density coatings.

The HV 3000 Powder spray system applies powder sprayed coatings to almost any grit-blasted surface, whether metal, wood or plastics. Laboratory testing on evaluation facilities at the company provide customers with recommendations and parameters to assure optimal spray yield and coatings of the highest quality.

Unlike water-cooled HVOF systems the HV 3000 Wire/Powder uses compressed air as a cooling agent, eliminating weight and easing operating conditions.
